Totll whom, z'l r11/ffy concern.:

B e it known that we, WILLIAM H. BUTTER- WoRrrI and JOHN BUTTERWORTH, Jr., citizens of the-UnitedStates, residing at Trent0n, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Thrashing Machines, .of which the following is a specification, reference being had therein to the accompanying m drawings, in whichv Figure 1 is an elevation of one side of our .improved thrashing machine, parts of the stacker of which are broken away, Fig. 2 is a section taken vertically and longitudinally throughthe machine, the stacker proper being detached.

Our invention relates to th at class of thrashing-machines and graincleaners combined which are knownas vibrating thrashers;77 and it consists in certain novel improvements 4o on such machines, which will be fully understood from the following description when taken in connection with the annexed drawings and claims.

Our machine is constructed with the rear 1,5 end extended beyond the sills, for the purposeof supporting the rear end ofthe vibrating shaker and the rear part of the strawrakes. such manner as to set these rails on an inclined 5o plane, which makes a substantial support for The extension-rails A are arranged in l beyond the rear sills, B, thereby dispensing with legs or props heretoforeused. By thus extending the rails or beams beyond the vertical plane of the sills B,we afford afree space for readily removing the chaff, which continuallyaccumulates beneath said extension when the machine is in operation.

B B are the sills of the machine, which are v in the same horizontal plane, but separated 6o by a space which `is strengthened and stiffened by arched plates B2, securely .fastened to the outside of the sills, and also to uprights, which constitute a portion of the frame, as shown in Fig. l. This transverse arch, formed 6 5 bythe divided sills and the stiffeningplates, affords reception for the front wheels in turning the machine short around.

D designates the thrashing-cylinder, which is suitably spiked, and E is the concave,which 7o is shown in Figs. 2 and 5. A

F designates the feedtable, which is arranged in front of the cylinder Dto receive the grain in the straw preparatory to its `being beveled edge, a, which will deflect or direct the current of air (which accumulates in the semi-cylindrical casing below the cylinder D by the revolutions of said cylinder) through the strawv as it is fed between the cylinder and So the concave, and thus create avacuum or sucking in of the dust from the feed'table and from the face of the person who feeds the -straw to the machine.

Gis the cylinder-casing, inside of which the 8 5 lower half of the thrashing-cylinder is situated. The rear end of the feed-table F is eX- tended over and within lthe circumference of the cylinder-casing G, beveling this end a, as described. This beveled end a also serves to 9o deect the wind produced by the revolution of the cylinder D downward and back -into said casing, thus producing eddies therein and keeping the chaff and dust down.

The concave E is pivoted or hinged at its 95 front edge, so that by means of a handle, H, and a cranked pivot, the former having a slotted arc, c, the rear part of this concave can be raised entirely out of the way of the toothed thumb-screw, c', which is tapped into an offs'ct, 0*, of the pivotal bearing, the said lever thrashed. This table is constructed with a Y cylinder D when desired. -By means of aroo raised ora depressed position. In front of K this concave is a cover, m, having a hinged it and rake close to the cylinder.

`Vdnstdeflector, oz.

I designates the upper vibrating shaker, which is in rear of the cylinder D, so that the grain in the straw, as it leaves the cylinder and concave after being thrashed, will fall into this shaker. The shaker I has two inclined bottoms, the upper one, e, being made of perforated sheet metal, and the lower one, c, being an ilnperiorated board. After the strawis thrashed, it is moved over the perforated bottom c by a series of rakes, J having curved and straight teeth on their under sides, said rake-bars being hung from cranks J', which give them the proper movement for raking the straw from the thrashing devices and discharging it upon a stacker, hereinafter explained. The cranks J are formed in such manner that the two extreme side bars, J 2, 0f the raking apparatus work in unison with each other, while the intermediate rake-bars, J, work on different quarters of the stroke. The object of this is to avoid the necessity of slotting the iiexibleapron or dropboard K to allow the rake-bars to reach the point of delivery from the thrashing-cylinder for the purpose of raking away the straw that accumulates on the shaker I between said dropboard and cylinder. It will be observed that by our invention of making the two side bars work in unison with each other we are enabled to have them pass along the sides of the drop-board K and be connected together by a cross-bar, L, between theJ said drop-board and thrashingcylinder. This cross-bar is provided on its under side with a row of straight teeth, a', which, when the cranks J are set in motion, rake the straw under the drop-apron K, while the other rake-teeth J, on the rear side of the drop-apron, reach the straw in their revolutions or stepping motion, and continue to rake the same out of the body of the niachine.

A thin metallic arm, a3, is rigidly secured to each side of the raking apparatus, which arms allow the openings at the ends of the dropapron to be made quite small. If desired, the rake-bars J 2 may be extended forward to serve as a substitute for the said thin arms. IVe hang each rake bar or frame on the under side of the cranks, and attach these bars or frames to their cranks by means of caps so that, in working, the wear of the journals comes on the said caps and not on the rake-bars, thereby greatly increasing the durability of said rakebars.

The cross-bar L is provided with a row of hooks, a, which will rake close to the thrashing-cylinder D and prevent this cylinder from winding when thrashing wet straw.

Immediately in rear of the thrashing-cylinder is appliedahinged self-adj usting deiiector, M, which is slotted, as shown in Figs. 2 and 10, to allow the straw-hooks a5 to pass through This deiicctor keeps the straw down and aids in preventing it from rising over the raking apparatus.

O O are the side boards on which the top of the machine rests. The upper edges of these boards are inclined forward, corresponding to the inclination of the rake-bars J,for the purpose of having the top or cover of the machine an equal distance throughout its entire length above the said rake-bars J, thereby preventing the straw from working on top of the rakes on its way from the thrashing-cylinder to the discharge endof the body of the machine.

P designates the duster, which is located over the thrashing-cylinder and its concave. This duster has a iiue through it in the usual manner, the mouth of which is directly over the feed-table F, and it extends back of the cylinder D. In this (luster is a fan, j), ex-

tending its entire width, the upper part of which revolves in the dust-flue. Just in front of the fan j; isa board, p', having its upper edge or lip directed toward the fan-wings. By thus constructing and arranging the board p, the currents of air will be deflected back, which will tend to produce avacuum or sucking in ot' the dust, &c., at the mouth ofthe lue, which is then caught by the fan-blades and forced out ot' the rear ot' the Hue. This fan p is rotated by means of a cord or beltn passed around apulley dn the thrashing-cylinder shaft, L id' also around a pulley on the fan-shaft.

The thrashingeylinder D is provided with boxes d, which. are constructed with ears, through which bolts d2 pass, the inner ends of which are rigidly secured to the sides ot' machine, and their outer ends are provided with nuts, which bear against the ears of the boxes, so that by loosening the screws which pass through slots and hold the boxes down, and turning said nuts, the thrashingcylinder can be adjusted endwise or held firmly against any side orlateral movement. Thus the teeth ofthe cylinder will pass between the teeth of the concave centrally and without any lateral play when the cylinder is revolving.

The upper vibrating shaker, I, contains the perforated sheet-metal riddle or bottom, and also the imperforate bottom, so that the grain and chaff are separated from the straw, and pass through the perforated metal bottom and descend onto'the inclined imperforate board bottoni e to the lower shaker, I', which contains the sieves for separating the chaff, &c., from the grain. The upper vibratin g shaker, I, and the lower vibrating shaker, I', have longitudinal vibrating motion in opposite directions communicated to them by means of a double ec! centric on the shaft N of the fan V, acting through the medium of Pitman-rods R, which areprovided with boxes r1", constructed with cars to receive bolts that secure them to said rods. These boxes o' 1" are each less than half of a circle, so that they can be adjusted toward each other, in case of wear, without the necessity of removing them and filing oftl their edges. The pitman-rods R are also provided ICO IIO

. with metal straps r2 r3 .on top and bottom, through slots in which pass metal keywedges r to take up lost motion caused by wear. These key-wedges are heldin positionby making the top straps in thefform of clamps, which are adjusted by means of bolts r4, applied at the backs of the wedges.

At. the'rear end of the machine, and over the upper vibrating shaker, I, is placed anadjustable hood or cover, S, for the purpose of directing the delivery of the straw tothe elevator. This hood is hinged to the top of .the back cross-bar of themachine, and is provided at each end with a slotted segment, S', through whichl a bolt passes that is fast to an upright metal post, S2. These bolts are also tapped through small clamps on the inside of the said posts, so that by loosening the bolts the hood S can be adjusted at any desired angle, and then held firmly byscrewing up said bolts. Another object of the hood S is to prevent wind-blast from entering the tail' of the machine and blowing dust, Svc., back land re tarding the discharge of the straw. It is important to provide means for adjusting the hood and rigidly securing it at different a11- gles, according to amount of work being done. This we do by the device above described.

T designates the 'fan-case, in which the fan V revolves for cleaning the grain. This fancase is constructed with a removable front section, T2. The fan is secured to the shaft N, so that by the revolution of this shaft wind is drawn into its case through end openings and forced out of the trunk through the sieve in the lower vibrating shaker, I'. The ends of the fan-shaft N are supported by j ournal-boxes N', which are rigidly secured to two of theuprights of the main frame,and which iuclose longitudinally-split bushings rl, which latter can be contracted about the journals of shaft N by means of set-screws r3, tapped through the boxes N', and bearing against the bushings near their splits. By this means we are able to compensate for the wear of the journals and bushings, and by means of passages N2 we are able to supply oil to the j ournals and their bushings. The fan-case T is provided at the end openings for the influx of air with adj ustable slides T', which are moved by means of a horizontal transverse shaft, WV, which is journaled in brackets which are rigidly secured directly to the front removable section, T2, of each end of the fan-drum. The removable section of the fan-drum, having connected to it the slides for regulating the draft, as also the looped racks and the shaft, which carries the pinions which work in said racks, it will be readily seen that when said section of the fan-drum is removed the other parts accompany it, and are thus kept together, all being easily separated from the main body of the machine. This shaft W is provided with two pinions, W2, which engage with racks W', attached to the said slides T'. Hand-wheels are also applied to 4the ends of the shaft W, so that the operator can turn this shaft from either not -in immediate use.

side of the machine, and thus by adj ustingthe said slides together regulate the size of both openings at the ends of the fan-case, and consequently'the admission of air therein.

X is the front board or platform, on which the operator stands to feed the machine with grain in the straw. This platform is constructed with a slatted bottom, leaving a space between the slats and the footboard, and a slat in front thereof, thus forming a pocket, x, adapted to receive eXtra sieves, Ste., that are The arms. of the plat form X are connected by links X' to the front s ill`s,B', of the machine, and sustained in ahori zontal position by means Vof chains Xl and from by the blast'of the fan V. This screenv is constructed with a band, b, or other imperforate smooth surface at its upper part, for the purpose of preventing the cheat or cockle from falling behind the trough G.

Z Z Z is the straw-stacker, which is composed of sections of suitable length jointedtogether, so that they can be folded in a small space when not in use. The-first or 4lowest section Z is attachedrigidly tothe frame of the machine, and provided with a hinged door, g, in its bottom, held up by a'button, q'. This door may be open or shut during the operation of the machine, for the purpose of delivering the chaff, either separate from or together with the straw, in the stacker.

The usual endless slatted carrier is composed of belts and slats passed aroundrollers in the usual' well-known manner, the lower roller being driven by a belt applied to beltwheels. (Not shown in the drawings.) The first folding section of the stacker isconnected to the rigid section by means of slotted or loose hinges l1., which will allow this section, together with its folding fellow, to be adj usted to a higher angle than could be done if the hinges were not slotted, thereby enabling usv to build very'high Aand very long stacks. When the said section of the stacker has been adjusted as desired, the joint is made rigid by means of a set-screw, h. v

It will be seen by reference to Fig. 1 that the stacker can be raised or lowered to any desired angle by means of ropes or chains k, connected to the rearmost section of the ICO IIO

stacker and to a windlass, L', which is on top of the machine, and which is provided with a ratchet and pawl, as shown in Fig. 1,

for holding the stacker at any desired angle.

It will be seen also by referenceto Fig. Zthat we apply a hinged guard, g, to the front end of the duster P, which serves as an additional security to prevent dust from flying into the face ofthe operator while feeding the machine.

Q, Q are the inclined spouts, one of which is for discharging the tailings, 'and the other is designed for discharging the clean grain.
